HENRY GOODENOVV, OF MO NTROSEJVVISGONSIN.

COMPOUND METAL-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 356,118, dated January 18, 1887.

Application filed June 1, 1886. Serial No. 203,852. (No model.)

To all whom it may COiZCGFIZ:

Be it known that I, HENRY GOODENOW, a citizen of the United States, residing at Montrose, in the county of Dane and State of \Visconsin, have invented certain new and useful Improvements in Combined Punching, Shearing, and TireSh rinking Machines 5. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement in combined punching, shearing, and tire-shrinking machines, especially adapted for the use of blaeksmiths, all as set forth in the following specification.

Figure 1 is a side elevation of my combined machine. Fig. 4. is a transverse section of the same through the line 00 m. Fig. 2 is 'a longitudinal vertical section through the machine on the line g Q] 3 of Fig. 4. Fig. 3 is an end view of the machine as shown in Fig. 2.- Fig. 5 is an elevation showing the relative position of the parts on the tire-shrinking device when the hand-lever is up, as shown in Fig. 2.

In the drawings similar letters where they occur refer to like parts throughout the several views.

The frame-work of the machine may be either of separate castings properly secured, or preferably, as shown in the drawings, it may be a single casting properly cored to admit the slide-bar and angle-lever, hereinafter described, the longitudinal central supportingrib being designated by B, and the respective vertical frame-pieces of said casting extending therefrom on either side of the same I designate, respectively, by A. The angle-lever L, pivoted at 19, between the two upright portions A A, extends through the whole length of the machine, its forward end projecting somewhat and being slotted to admit the hand-lever O, pivoted at its lower end to the forward-projecting end of the rib B, and operatively connected with the angle-lever Lby the links Z Z, between which said links said hand-lever is adapted to pass freely. The knife a,bolted to the anglelever L, and the knife I), similarly bolted to the rib B,-are adapted to be operated as metal shears-the forward or straight cutting-edges for cutting sheet and plate metal, and the rear or curved edges for cutting rods.

In order to prevent the knife (I. and lever L from being deflected when cutting heavy work, I provide the lever L, at its forward end, with a guide-extension, g, fitting closely, but adapted to reciprocate freely between the opposite inner faces of the frame-castings A A. The rear lower arm of the angle-leverL also serves the same purpose to a considerable extent. Between the inner vertical faces of the upper part of the frame-pieces A A, I insert the horizontal bar D, having a series of upward extensions, I, provided each with a metal punch, c, properly secured thereto, said bar being adapted to reciprocate horizontally on' the bolts 01 d, extending through the sides A A and the horizontal slots (1 d of the bar D. The punches c are preferably of different sizes, and may be either permanently set in the extensions I or so adjusted therein as to be removed when so desired.

I do not restrict myself to any particular number-of these punches, as itis obvious that the machine may be constructed with reference to a greater or less number of them as desired. The work to be punched is placed against the face-plates or punch-blocks e, suitably pierced longitudinally to admit the forward end of the punch as it passes through the work and allow it to force the waste material through and out of said longitudinal aperture.

The punclrblocks a may be bolted, dovetailed ,or fastened between the inner vertical faces of the frame-pieces A A in any usual man- ".ner, the latter being provided at proper intervals with suitable transverse slots, f, for receiving the work to be punched, the forward slot, f,

being adapted to receive broader sheets than the former to force the punches through their work and through the latter to retract them. The pivot-block E, resting in curved seats in upward extension of the lever L, respectively, is held in position transversely by the tie-strap h. (See Fig. 1.)

the rear end of the bar D and front face of the The lower end of the arm F, pivoted to an extension on the upper forwardend of the frame A, is operatively connected with the lower rear extension of the angle-lever L by means of the tie-rod R, and is further [secured at its lower end by the headed guide-pin i, eX-

- tending through the arc-slot j of the arm F into the central supporting-rib, B. By this means the arm F is prevented from deviating transversely in the process of shrinking the tire. It is further provided with the curved seat m rigidIy secured to its outer face, and with the dog 70 pivoted to the same. The dog 70 is similarly pivoted to the adjacent corresponding face of the frame A, which face is also provided with the curved seat m, rigidly fastened thereto.

The dogs 7a 70 are constructed with wide steel chisel-edges sufficiently sharp to engage readily and hold against the tiresurface. In the drawings the face of the dogs is k is represented as upset, in order conveniently to ob tain the transverse chisel-edges; but I make no claim to any particular form of dogs in this connection. The dogs k k are to be provided with hardened-steel ends, attached by welding or any other common device, and sharpened into comparatively wide transverse chiselfaces adapted to engage against and firmly hold the tire in position to be shrunk.

It has been the custom in the class of tireshrinkers herein described to use pivoted dogs having either toothed engaging-cams or com paratively narrow engaging-points. Neither of these devices, however, is as effective in holdingthe tire from slipping as is my device,

herein described, of providing each dog with a wide hardened-steel chisel-edge, which can be kept sharp more conveniently and at less expense than can the edges of a toothed cam, and holds the tire in position much more firmly, and, after the tire has been properly inches wide; but I do not wish to be under- I diameter will be about that of the average wheel-tire. The whole machine, as described, may be mounted on suitable standards or feet, and can stand on the floor or the ground, and is adapted to be operated by hand.

The tire-'shrinking'device is operated as follows: The tire,having been sufficiently heated, is placed on the upper curved surfaces of the seats on m. (See Fig. 5.) The dogs 7c are then set firmly against the tire on its inner surface to hold it from slipping, the heated portion of the tire being between the engaging edges of the same. (See Fig. 1. The operator then bears down on the hand-lever O, which motion, by means of the links ZZ and angle-lever L, is communicated through the tie-rod R, drawing the arm F,with the seat on, back against the seat m. During this operation the tire, being held rigidly by the dogsk 70 7c, is crowded or looped up at the heatedportion, and thereby lessened in diameter or shrunk. WVhile in this condition on the machine the loop or upset portion may be hammered smooth, so that when removed from the machine the tire is ready to be set. It is obvious that the operative power originally applied to the end of the hand-lever O is multiplied through the links Z Z and angle-lever L. At the same time that the operating-lever Ois 8o moved downward the lever L is drawn down, the knife a closing by the knife I), while the series of punches are pressed forward until their points enter the clearanceapertures.

I am aware that in tire-shrinking machines devices are in use wherein the tire is held by dogs in a curved seat consisting of two sec tions, one section being fixed and the other being adapted to be moved up against the fixed section, thereby upsetting the tire between the o engaging points of the dogs. Such arrangement I do not claim, broadly; but

\Vhat I do claim, and desire to secure by Letters Patent from the'United States, is-
